Abstract
A series of cells for use in an electrochemical device, such as an electrochemical cell or battery, that can operate in a single bulk electrolyte solution shared among the cells. Methods of producing hydrogen or both hydrogen and electricity in appreciable quantifies and in various ratios, and vehicles or other devices and applications powered by electrochemical devices comprising the series.
Claims13
A series of cells for use in an electrochemical device, which comprises:
- a first cell comprising an anode and a cathode current collector;
- and
- a second cell comprising an anode and a cathode current collector;
- wherein the cathode current collector of the first cell is in physical contact with the anode of the second cell,
- wherein each cell in the series comprises a conduit between its anode and cathode current collector, wherein the conduit of each cell extends from an inlet end to an outlet end in a direction along the length of the series,
- wherein the cells in the series form a chain with the outlet of each upstream cell aligned with the inlet of each adjacent downstream cell such that the conduits of the cells in the series together form a flow path extending from one end of the series and through the series of cells to the other end of the series, and
- wherein at least one cell comprises a convergent nozzle at the inlet end of its conduit,
- wherein the convergent nozzle reduces the cross-sectional area of the conduit of the at least one cell in the direction from the conduit's inlet end to its outlet end, and
- wherein the cathode current collector of the at least one cell is shaped to wholly or partially form the convergent nozzle.
